| Specification: |
Depending on purity, samples can appear yellow-green to grey. Phosphorus esquisulfide (1314-85-8) was discovered by G. Lemoine and first produced safely in commercial quantities in 1898 by Albright and Wilson. It dissolves in an equal weight of carbon disulfide (CS2). Unlike some other phosphorus sulfides, P4S3 is slow to hydrolyze and has a well-defined melting point. |
